IS 12027 : Part 2 : 2025 Water Repellents - Specification - Part 2 Silane Based
1 SCOPE
This standard (Part 2) specifies the requirements, testing methods, and guidelines for the use of silane based water repellents intended for use on the surface having sufficient porosity such as concrete, masonry, porous stones. This impart water repellence through penetrating deeply into porous materials and bonded chemically with the surface to form a hydrophobic barrier.
